Mechanical Muscle Proprieties in Patient with COPD

Chronic Obstructive Pulmonary Disease (COPD) leads to progressive airflow limitation and respiratory muscle dysfunction, contributing to exercise intolerance and reduced quality of life. While existing methods evaluate overall lung function, the assessment of specific respiratory muscle properties remains challenging. Myotonometry offers a non-invasive technique to quantify muscle tone and stiffness, potentially providing insights into respiratory and skeletal muscle mechanics in COPD. This study aims to explore differences in the mechanical properties of both superficial respiratory and skeletal muscles in patients with COPD compared to healthy controls using myotonometry. Investigators hypothesize that COPD patients will exhibit altered mechanical properties (e.g., increased stiffness and tone) in both superficial respiratory and skeletal muscles compared to healthy controls.
